For problems 3,4, and 5, Consider an egg that has a mass of 0.15 kg being held at the top of a flight of stairs. 3. If an egg has 11 J at the top of the stairs, what is the height of the stairs?

4. If the egg is dropped from that height, what is the Kinetic energy right before the egg hits the ground?

5. If the egg is dropped down to the ground from that height, what is the velocity of the egg right before the egg hits the ground?

An experiment was performed on a 2-kg block. forces of 5, 10 and 15 newtons respectively were applied to the block for 5 seconds. describe the difference in acceleration between the three trials. a) the final accelerations will all be the same. b) the final acceleration will triple between the first and third trial. c) the final acceleration will be cut by 1/3 from the first to third trial. d) the final acceleration will increase nine time between the first and third trial.
